UNETD STATE WILLIAM A. I'ECGLELLAND, OF BIDGEWOOD, NEW JERSEY, ASSIGNOR TO THE FUCHS z; LANG MANUFACTURING COMPANY, A CORPORATION OF NEVT YORK.

COLLECTOR RECEPTAOLE.

Application filed February 3, 1922.

To all whom it may concern:

Be it known that 1, WILLIAM A. MoCLnL- LAND, a citizen of theUnited States, residing 4. of

New Jersey, have invented certalni useful Improvements in Collector tacles, of which the following is a specification.

This invention relates to collector receptacles such as are particularly adapted to be usedin connection with bronzing machines employed in the finishing of lithographic prints.

An important object of the invention is to provide a receptacle particularly adapted to be used in the above mentioned connection, which is so constructed that such air currents as enter the same with suspended bronze particles may be satisfactorily relieved without loss of any portion of the bronze which is being collected or reclaimed for further use.

A further object of the invention is to provide a receptacle of the class mentioned which is simple in construction, inexpensive to manufacture, and reliable in use. 1 Further objects of the invention will become apparent from the following specification taken in connection with the accompanying drawings in which;

Figure 1 is a view in elevation showing the receptacle embodying my invention.

Figure 2 is a fragmental and somewhat enlarged sectional view taken on line 2-2 of Figure 1.

Figure 3 is a horizontal sectional view taken on line 3-3 of Figure 2.

Figure 1 is a fragmental and somewhat enlarged sectionalview showing certain details of the sealing diaphragm.

In the drawings wherein is shown what I at present consider the preferred form of my invention, the numeral 5 indicates a receptacle preferably constructed of sheet metal which, relatively near its upper end is provided with an outwardly projecting reinforcing bead 6 adjacent to which is formed an inwardly projecting bead 7 which also serves as a reinforcement and as a shoulder or seat adapted to receive a sealing diaphragm hereinafter more particularly referred to.

The receptacle 5 is provided with a closure, indicated as a whole by the numeral 8,

Serial No. 533,858.

which comprises a cover 9 to the overlying peripheral edge of which is secured a downwardly projecting flange or apron 10, which extends an appreciable distance below the per edge of the receptacle 5. A pair of openings 11 and 12 are formed in the cover 9 tance into the receptacle 5 as shown in Fig ure 2. Within the opening 12 there is arranged a relativel short pipe 16 which is adapted to be attached by any suitable means to the flange 1a. Upon the outer end of the pipe 16 there is arranged a cap ring 17 which is removable and provided with a screen 18 adapted to be held in position by a retaining ring 19 or any other suitable means. The pipe 16 extends an appreciable distance into the receptacle 5 and is provided at its lower end with a screen 20 which is similar to the screen 18 and held in position by any suitable means. The pipe 16 together with the screens 18 and 20 forms a receptacle into which is placed a filter such for example as waste 21 capable of preventing the passage of the bronze particles, which enter the receptacle with the air currents through the pipe 15 in a suspended condition, without retarding the flow or exit of air as the pressure within the receptacle tends to rise.

The closure 8 further comprises a sealing diaphragm. 22 having formed therein openings 23 and 24: adjacent to which are provided upstanding flanges 25 and 26 respectively. -The diaphragm 22 is suspended from the cover 9 by the pipes 15 and 16, the lower ends of which are projected through the openings 23 and 2d and secured respectively to the flanges 25 and 26 by any suitable means. At the periphery of the diaphragm 22 there is formed an angularly disposed flange 27 to which is secured a groove ring 28 which forms with the flange 27 an annular groove 29 into which is fitted a packing ring 30 preferably of felt material. The material from which the ring 30 is formed is folded upon itself, as shown in Figure i, and is retained, within the groove 29 by means of a locking ring 31. By this construction the packing ring 30 is securely retained in such a position that when the closure 8 is placed upon the receptacle 5 a tight seal is afforded between the sealing ring 22 and the receptacle 5 by reason of the intimate contact of the sealing ring 3%) with the inwardly disposed bead or seat '7 upon which it is retained.

In use the receptacle 5 is placed in such a position that the pipe, not shown, leading from the equalizing receptacle, also not shown, may be inserted into the pipe 15 whereupon the closure 8 is lowered upon a receptacle 5 to the position shown in Figure 2 thus estal' lishing a sealed relation between the diaphragniQQ and the container. As the bronze particles are uriven into the equalizing chamber, not shown, they are allowed to pass therefrom illl'Orlgli the pipe 15 into the receptacle 5 together with a relatively small amount of air which is not expelled into the atmosphere directly from the equalizing receptacle. By reason of the fact that the bronze particles are relatively heavy they fall to the bottom of the receptacle 5 whereas the air currents which enter the receptacle are allowed to escape into the atmosphere through the relatively short pipe 16 and the filter 21 which serves to col lect or prevent any oil the bronze particles from escaping which may fail to settle at the bottom of the receptacle.

While I have shown what I at present consider the preferred form of my invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

I claim:

1. The combination with a receptacle havinga diaphragm receiving seat, of a closure for said receptacle, said closure comprising a cover, an entrance conduit passed througl'i said'cover and attached thereto, a sealing diaphragm suspended from said cover and attached to said entrance conduit, a sealing ring attached to said diaphragm and adapted to rest upon the seat of said receptacle, and an exit conduit leading from the interior of said receptacle to the exterior thereof.
